It's possible, though they aren't currently recorded, so the best we could do is high score since implementation (i.e. if I implemented it today, it would show your high score from today on)

there is no way to data mine the historical games? maprank comes up with a high score so couldnt you do something similar?

We can data mine the old games, however some games are missing game logs due to a server mishap, so those couldn't be recovered. The problem with data mining in this large of a dataset with this many parameters (we'd have to mine for every user on the site), the amount of time and processing power required would be unrealistic. I'll keep looking into it to see what we can do.

Simply tap into your fellow conquerclubbers' computers voluntarily, and they'll do the heavy lifting for ya. Depending on how long the processing takes, one could do a refresh once a week, month, or whatever.
